Squeezed-light enhancement and backaction evasion in a high sensitivity optically pumped magnetometer
C. Troullinou, R. Jiménez-Martínez, J. Kong +2
We study the effect of optical polarization squeezing on the performance of a sensitive, quantum-noise-limited optically pumped magnetometer. We use Bell-Bloom (BB) optical pumping…
Heading errors in all-optical alkali-vapor magnetometers in geomagnetic fields
W. Lee, V. G. Lucivero, M. V. Romalis +3
Alkali-metal atomic magnetometers suffer from heading errors in geomagnetic fields as the measured magnetic field depends on the orientation of the sensor with respect to the field…
Femtotesla direct magnetic gradiometer using a single multipass cell
V. G. Lucivero, W. Lee, N. Dural +1
We describe a direct gradiometer using optical pumping with opposite circular polarization in two Rb atomic ensembles within a single multipass cell. A far-detuned probe las…
Portable magnetometry for detection of biomagnetism in ambient environments
M. E. Limes, E. L. Foley, T. W. Kornack +6
We present a method of optical magnetometry with parts-per-billion resolution that is able to detect biomagnetic signals generated from the human brain and heart in Earth's ambient…
Correlation function of spin noise due to atomic diffusion
V. G. Lucivero, N. D. McDonough, N. Dural +1
We use paramagnetic Faraday rotation to study spin noise spectrum from unpolarized Rb vapor in a tightly focused probe beam in the presence of N buffer gas. We derive an analyt…
